I have a K3 / P3 / SteppIR SDA100. Everything is set to 38400 baud. I
have connected a Y-cable to the RS232 connection on the K3. One side of
the Y is connected to the SteppIR controller with a null modem inserted
(as directed by SteppIR instructions). The other side is connected to
the XCVR connection on the P3. Both work, but not at the same time.
Unplugging one of the Y connections makes the other work, and visa
versa. Any ideas? Perhaps there is a special & splitter that will
provide the necessary isolation?? Or perhaps I need to orient the Y a
different way??
